Abstract

In an electromagnetically actuatable fuel-injection valve for injection systems for internal-combustion engines, the valve includes a valve housing, an ejection opening, a magnet winding, a closure element which is connected to an armature associated with the magnet winding, and a pin which is located in the ejection opening and has a conical region, the conical region being within or at a plane formed by the outer edge of the ejection opening. In this way, the formation of drops at the edge of the ejection opening is prevented so that a fine atomization is obtained.
